I want to say Thanks for sharing your feelings. I am also working on relationship problems with my husband. Its nice to read a mans point of view, because its hard for me to get much out of my husband.
Recently, we started something that has really helped our relationship. We call it 3 in 30. Every night before bed, we take 30 minutes to discuss 3 issues that we have with eatch other or about ourselves or even what happened that day. Then we pray together. Its really a learning experience. I love it because I know we have 30 minutes together just to talk.
Im glad that you haven't given up on your wife. I encourage you to stick with it.
